To all whom z't may concern.'

Be-it linown'that we, CHARLES S. HERSH and CHRISTOPHEEJ. OiGON-NOR, citizens of the United States, residing at'Philadelphia, in the county of Philadelphia and vState of Pennsylvania,have invented new andvuseful Improvements in Non-RefillablerBottles, of which the following is aspecication.

This invention lrelates to bottles, and has particular reference to the Vnon-refillable type.

An object of thel invention is to v'provide a bottle with mechanism for preventing Ythe refilling thereof after the original contents v have been withdrawn.

A further object is to provide a bottle with an attachmentfor'rendering the bottle non-rellable, said attachment consisting of fewand simple parts, which can be cheaply manufactured and easily assembled, and capable of positive operation.

The invention broadly comprises a gravity valve for closing the neck of the bottle when the'latter is upright, and vithin the valve chamber a float above the lvalve and a ball weight above the lioat, -both appreciably smaller than the chamber `and positively closing the valve when the bottle isupright, but the float adapted to be movedout of alinement between the `ball and valve when the bottle-neck is horizontal, so as to thereby prevent the bottle from being refilled Vby submerging it.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will be exemplified in the constructionJ herein described and the scope of the application of which will be indicated in the following claims In the accompanying drawings, wherein is illustratedI one of the Vpreferred forms of the invention Figure 1`is a fragmentary vertical sectional view of a bottle illustrating the application of a non-refillable attachment hereto.

Fig. :2 is L similar view illustrating the bottle in an inverted position.

Fig. 8 is a horizontal sectional view on the line 3-3 of Fig. 1,

Fig. 4 is a similar view on the line 4 4 of Fig. 1, and

Fig. 5 is a perspective view of the valve mechanism in separated position.

v Referring more'particularly to thel draw-` ings, the numeral 1I designates a bottle body formed with .the v usual .necky '2 which is provided with anenlarged annular-"rim 3, formed withan annular groove 4. -A :head

5, `preferably formed ofl porcelain, 4is'su'perposed upon the rim 3, and is normally'spaeed therefrom by a washer; or valve seat- 6,' in

which'is for-med a central opening 7. The

vhead 5-is further provided with a circulan oiset 8 and-surrounding the latter andthe enlarged rim 3 of theneck 2 is a metallic Vsleeve 9, which'rigidlysecuresthe head 5 to the bottle by having the'lower.y end fofthe sleeve spun into the. groove 4 on the rim andl except for an opening 11 through which ythe liquid'passes when escaping from the bottle.'y Vithin` the porcelain head 5 is a valve chamber 12 inwhich are formed a series of spaced radially extending ribs 18. The lower ends of the ribs are beveled to enlarge the chamber 12 and to permit agravity valve 13a to have sufficient vertical movement toy open or close the opening 7 in the valve'seat 6. The

' valve 131Vis-of substantially inverted cup shaped formation and is normally held uponits seat 6 by the action of a spherical weight 14 forcingdownwardlyupon a cork rmember 15, both loose within theribs 13 and the cork normally resting upon'the valve 13a. The upper extremities of the ribs 13 are provided with wings having converging edges or faces 16 for a purpose to be presently set forth andl positioned above said ribs isa baie plate 17 having the periphery thereof formed with a plurality of openings 18 in alinementwith the channels 19 betweenthe ribs 13. It is to be understood thatywhile the head, ribs, and baffle have been'described and shown as'integral,

it is possible to form the same in separate sections and connectthem in' any suitable manner. In cross-section both the ball and the cork are appreciably smaller than the space inelosed by the inner edges of the ribs, as will be seen in Fig. 4. The result is that the ball is loose Within the chamber excepting when it rests on the inner edges of the wings, and the cork would be loose within the chamber excepting for means which we provide to keep it normally concentric With the valve. These means include a convex dome 22 on the top of the valve as best seen in Fig. 5, and a concave socket 23 in the lower end of the cork normally engaging with the dome as best seen in Fig. 1; and When the cork moves laterally out of its normal concentric position, it increases the distance between the dome and the weight.

In operation, when the bottle 1 is in an upright position, the valve 13 rests upon the seat 6 and covers the port or opening 7 and is retained in this position by the action of the spherical weight 14. However', when the bottle is inverted, for instance to an angle of thirty degrees, the weight 14 drops onto the wings and perhaps rests upon the battle plate 17. This action permits the cork 15 to follow the weight and the valve 13 to open, so that the liuid contained within the bottle may escape through the port 7, around the circumference of the valve 13a and into the chamber 12, passing through the channels 19 and out of the head 5 by way of the openings 11 and 18. One of the salient features of this device resides in the rapid and positive operation of the valve 13a. It will be noted that the inclined faces 16 of the Wings arrest the movement of the weight 14C until the bottle has been nearly inverted to a pouring position. After the bottle has reached a certain tilted position, the weight 14 will gravitate into the conical socket formed by the inclined faces 16, thereby relieving the pressure upon the valve 13EL and permitting the same to open.

If a fraudulent or unscrupulous attempt should be made to rell the bottle by submerging the same when horizontal, the inflowing liquid will surround the cork member 15 which, by its buoyancy, will float upwardly and close the valve 13a, thereby effectively preventing the bottle from being refilled. Such closure of the valve occurs usually by the then upward movement of the whole of the float or cork, so that the concave seat or socket 23 moves out of alinement with the convex dome 22 and thereby increases the distance between the valve and the weight. As the float rises the weight falls, and when such distance is increased the weight is pushed toward the wingsremembering now that the parts shown in Fig. 1 stand substantially horizontally. Any tendency to roll the Weight up one of the inclined wings meets with resistance, and therefore the Weight pushes on the ioat and the float -(now off-center) pushes the valve to its seat. If, however, the disposition of the bottle neck should be such and the flow of liquid such that the iioat tilts or rises at its outer end, yet its inner end rolls `or rocks where it contacts with the dome 22, and the ball weight is still pushed axially within the head. The results are practically the same if the parts are properly proportioned. The web 17 prevents the valve from being exteriorly operated. The valve is freely disposed in the valve chamber, so as to return to a closed position when an exterior pressure of Vliuid or some other medium is proj ected into the mouth end of the valve chamber, thereby preventing a practical or convenient refilling of the bottle.

it will thus be seen that there is provided mechanism in which the objects of this invention are achieved and all the advantageous features above mentioned are, among others7 present. The bottlek is positive in action, of few parts and simple construction. The valve mechanism can be readily formed and assembled, and the movable parts thereof are so positioned that they cannot very readily get out of order, as by binding or becoming broken. Y

Having thus described the invention, I claim In combination with the neck of a bottle, a cylindrical casing secured upon the end of the neck thereof in end to end relation therewith and having an apertured outer end, a washer disposed between said neck and said casing and having an opening therein, an inverted heini-spherical valve seated upon said washer and normally closing the opening therein, radial ribs extending inwardly from said casing and extending from the bottom thereof to a point adjacent the top thereof, a baflie plate seated upon the upper ends of said ribs, a float slidable loosely within said ribs and concaved on its bottom face to engage said valve, and a weight disposed on said float and an outwardly extending iiange on said valve, the inner end portions of said ribs beingreduced and guidably engaging the fia-nge on said valve, to prevent lateral displacement thereof when said valve is unseated.

ln testimony whereof we affix our signatures.
